DOOR REMOVAL
1. Remove the side and top panels, top and bottom
plugs, control panel, and perimeter trim piece.
2. Remove the interlock actuator bracket (#3)
and front guide block assembly (#9) from both
sides of the oven.
NOTE: The guide block assembly may or may
not contain guide block support shims
(#22). Guide block assemblies should
be re-installed in the location they were
removed from (i.e. right guide block as-
sembly re-installed on right side) to pre-
vent potential trailing arm binding.
3. Close the oven door and disconnect the
springs (#8) from both trailing arms (#2).
4. Loosen but do not remove the nuts (#10) that
hold the cam follower assembly (#12) in posi-
tion, then rotate both assemblies down to verti-
cal orientation.
5. Remove the door:
F.) Remove the four 10-32 UNF Phillips screws
(#15) from the door hinge bar mounting
brackets (#13) on both sides of the oven.
G.) Pull the door away from the oven, bottom
first, to slide the hinge bars (#14) out of
their slots. Use caution in removing the
door to avoid bending the hinge bars. If the
bars bind in their slots, gently wiggle the
door to free them.
H.) Remove the door, guiding the hooked por-
tion of the trailing arm over the cam follow-
er rollers (#11).
DOOR INSTALLATION
1. Rotate cam follower assembly (#12) down to verti-
cal position to permit the trailing arms (#2) to pass
over the cam follower roller (#11) in step 2.
2. Assemble the door to the oven:
A.) Slide the trailing arms through the upper
slots and over the rollers.
B.) Slide the hinge bars (#14) through the
lower slots. Use caution in installing the
door to avoid bending the hinge bars. If the
bars bind in their slots, gently wiggle the
door to free them.
C.) Attach the bars to the door hinge bar
mounting brackets (#13) with four 10-32
UNF screws (#15) on each side (finger
tight). Apply thread-locker to screw
threads prior to installation.
D.) Close the door and apply even pressure
(approximately 15 to 20 pounds) to the face
of the door to squarely seat the door shunt
on the oven face. Continue to apply this
force while tightening the four screws on
each side (two people are recommended).
3. Install the spring (#8) on each side between
the trailing arm and spring bracket. Any inter-
ference between any other component or wir-
ing and the springs or trailing arms must be
corrected before proceeding.
4. Install the front trailing arm guide blocks (#9):
A.) Assemble (per side) one spacer block
(#17), two guide blocks (#18), two
spacers (#19), and two screws (#20) with
lock-washers (#21).
NOTE: The guide block assembly may or may
not contain guide block support shims
(#22). Guide block assemblies should
be re-installed in the location they were
removed from (i.e. right guide block as-
sembly re-installed on right side) to pre-
vent potential trailing arm binding
B.) Install one guide block assembly over
each trailing arm and tighten screws.
5. Install the interlock actuator brackets (#3):
A.) Open the door.
B.) Attach the interlock actuator brackets to the
trailing arms with two 6-32 UNC screws
(#4), nuts, and lock-washers on each side.
NOTE: As you face the oven front, the right-
hand side bracket is mounted to the in-
side of the arm; the left-hand side
